The inventor of PixelBlaze has some real cool routines as demonstrated at:
Has anyone tried to port any of these to FastLED? Apparently he’s using floating point math, with values typically ranging from 0 to 1.
I had a quick look, his code is not yet open source. It looks like he’s planning to share it in the future.
Really like that quick interactive preview interface.
I ended up ordering one from his Tindie site. Here’s a better look at those patterns and the previews:
@Andrew_Tuline , what do you get when you order? Have you experimented with it a bit now? Any more thoughts?
@marmil Hi Marc, haven’t got it yet, but will let you know when it arrives. Feel free to email me at atuline@gmail.com. In the meantime, I’ve been looking at his floating point display routines and trying to translate some to 8 bit FastLED. I like how he uses v=vvv on the brightness as well as using multiple timers, t1, t2, t3, etc. So, I’m just playing around. . . 
@Andrew_Tuline Cool, yes I was thinking some of that looked like it could be converted. 0-1 would become 0-255, etc. 
That’s exactly what I’ve been doing, so:
v = vv // with a range of 0-1 in PixelBlaze would translate to
v = vv/255; // with a range of 0-255 in FastLED
The PixelBlaze arrived today and it can either be configured as an AP or as a WiFi client. If you mess it up, it’s easy to reset. Once configured, the web interface you see is almost identical to:

That being said, I prefer the functions and programming of FastLED (time invested and all), but that web interface with on-the-fly programming along with the AP functionality are pretty nice.
Yes, the interface is definitely a draw.
Awesome, because it’s so easy to use.
